Detect tap and hold on iOS Keyboard Keys

Question

I'd like a custom method to be fired when I tap an hold a given key on the keyboard of the iPhone. It would also need to override the alternate character pop up.

Where should I start with this? I haven't tried anything too hackey in iOS yet

Answer 1

it's not possible in non-jailbroken iOS. Also, it may not be a good idea, as this only makes sense on QWERTY keyboard. For example Japanese iPhone keyboard would be impossible to use without tap to hold and Chinese keyboard has drawing area instead of keys. – porneL Jul 20 at 12:53
